Wireless connectivity added to Raspberry Pi 3 Model B+ IoT single board computer

Cypress Semiconductor has unveiled a Wi-Fi and Bluetooth combo solution that delivers robust wireless connectivity to the new Raspberry Pi 3 Model B+ Internet of Things (IoT) single board computer.

The CYW43455 single-chip combo provides high-performance 802.11ac Wi-Fi for faster Internet connections, advanced coexistence algorithms for simultaneous Bluetooth and Bluetooth Low Energy (BLE) operations such as audio and video streaming, and low-power BLE connections to smartphones, sensors and Bluetooth Mesh networks.

The combo’s high-speed 802.11ac transmissions enable improved network performance, faster downloads and better range, as well as lower power consumption by quickly exploiting deep sleep modes. The Raspberry Pi 3 Model B+ board builds on the success of existing Raspberry Pi solutions using Cypress’ CYW43438 802.11n Wi-Fi and Bluetooth combo system-on-chip (SoC).

Wi-Fi networks powered by 802.11ac simultaneously deliver low-latency and high-speed with secure device authentication, making it the ideal wireless technology for connecting products directly to the cloud.

The Raspberry Pi 3 Model B+ board with the highly-integrated CYW43455 combo SoC allows developers to quickly prototype industrial IoT systems and smart home products that leverage the benefits of 802.11ac.

The Raspberry Pi 3 Model B+ board features a 64-bit, quad-core processor running at 1.4GHz, 1GB RAM, full size HDMI and 4 standard USB ports, Gigabit Ethernet over USB2, Power over Ethernet capability, CSI camera connector and a DSI display connector.

The Cypress CYW43455 SoC features a dual-band 2.4- and 5-GHz radio with 20-, 40- and 80-MHz channels with up to 433 Mbps performance. With fast 802.11ac throughput it allows devices to get on and off of the network more quickly, preventing network congestion and prolonging battery life by letting devices spend more time in deep sleep modes. The SoC includes Linux open source Full Media Access Control (FMAC) driver support with enterprise and industrial features enabled, including security, roaming, voice and locationing
